I was looking at some of the older posts regarding Accumix. We purchased a used Crestliner 2360 Eagle with a 1999 175hp Evinrude and a 1986 9.9hp Johnson for trolling. Couldn't get gas to the engine and found out that the Accumix tank was the problem. I abandoned the Accumix and went to a 50:1 mix in a 6 gallon tank. The 9.9 runs fine, but there are a few issues I see with it. First thing I noticed after lengthy trolling periods was after i got home there was a heavy milky oil deposit inside the exhaust hub in the prop. As it sat for 3 or 4 days this would eventually ooze out on the ground. Should I be running a leaner gas/oil mixture than 50:1 since the Accumix tank mixed at 100:1? I'm in the process of changing the thermostat because the engine temperature is barely luke warm. According to information I found online, the thermostat temperature is 143 degrees F. At that temperature engine block/head should be uncomfortable to the touch. I also found heavy milky oil throughout the midsection and lower unit. I do not know how long this oily deposit has been inside this engine. I use Pennsoil XLF, TC-W3 rating. I am using the same oil in both engines and only have the oil sludge in the 9.9 Johnson only. Any help would be greatly appreciated.
